irrigation license

I just need to know if there is a requirement to be licensed in NC to install and inspect irrigation systems. I have been in the business for several years and have never been checked nor I have ever heard of of such a regulation. If anyone knows please let me know. Thanks

Call another irrigation company and ask them or call the water department in your city. Usually they want people licensed because of the backflow installation. Licensed plumbers are exempt. We are licensed here in Texas.
